CIRCUIT DISTRIBUTOR.

. Application filed February 11, 1920.

To all whom t may concern.'

Be it known that I, Romans N. Giusworn, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and y State of Connecticut, have invented certain new and useful Improvements in Circuit Distributors, of which the following is a speci- .tication This invention relates to circuit distributors such as are employed in connectioi'i with internal combustion engines.

T he object of the invention is to improve upon this class of devices by increasing the operative contacting surfaces and to form said surface so asto provide a more positive engagement whereby a more reliable electric connection will be produced; further to design the device with a relatively few parts in a manner to form a simp e and ellicient distributor.

lVith these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departure from the spirit or sacrilicing any of the advantages of the invention.

Similar characters of reference denote like or corresponding parts throughout the sev(- eral gures of the accompanying drawings forming a part of this specification, and upon which,

Fig. 1 shows a side elevation of my improved form of circuit distributor, and

Fig. 2 shows a sectional view of the same taken on line 2 2 of Fig. 1.

As illustrated in the drawings the mechanisin of the apparatus is adapted to be contained within a commercial type of casing adapted for use upon the camv shaft of certain well known types of cars. The parts, however, may be equally as well contained within other styles or forms of casings and upon other makes of engines.

Referring in detail to the characters of reference marked upon the drawings, 5 represents the metal casing referred to, which, as will be noted, comprises an annular cylindrical body portion, having one closed end 6 and an opposite open end. 'l' indicates a cam shaft shown in dot-ted lines, and as rep- Speeication of Letters Patent.

resenting part of a motor, and upon the end of which the distributor is designed to be placed. The rotator S is secured to this shaft by means of a. pin 9 and the hub portion of the rotator is obviously formed of metal as is also the radial extension 10 formed integ'al therewith. A metal shoe 11 is secured to this extension by means of screws as shown and is litted into a peripheral recess of the insulating rim 12 secured upon the hub and in line with the metal shoe 11, so as to provide a continuous annular peripheral operating surface. This periphery of the distributor is of an irregular shape in cross section. being preferably bevelled upon two sides forming an annular portion 18 of a greater diameter than the remaining surfaces 14C to form a broader operating face on the distributor than would be possible were it provided with a iiat face.

In connection with this central rotor provide a series of contacting rolls 15 the faces of which are substantially V-shaped to correspond with the operating peripheral surface of the rotator. There may obviously be any desired number of these contacting rolls which are suitably spaced one from the other to ride upon the periphery of the rotator. Each of these rolls are mounted in a bracket 16 that is preferably formed of spring sheet metal and whose inner ends are shaped to conform to the shape of the inner wall of the cylindrical portion of the casing, and is tensioned to form a yieldable pressing engagement on the periphery of the rotator. 17 represents an insulating member which is positioned between the bracket and the casing and 18 represents a screw that passes through the bracket and the insulating member as well as the insulating washer 19. 2O represents anut mounted upon each screw for securing the parts together and 21 indicates binding nuts by means of which the feed wires 22 are attached.

From the foregoing it will be seen that in view of the V-shaped peripheral engaging surface of the rotator and rolls I obtain a longer and rubbing connection between the same which insures a better electrical contact and forms a more durable construction.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

A circuit distributor including a rotatable shaft having an integral radial extension, a
